They would have their work cut out at CDD where half the plane has Sky Priority!
It does make me wonder if it is worth having a business class at all on these 1 hour flights. I've rarely seen it even half full and even if pax are travelling business class long haul from AMS and the NCL flight is thrown in for nothing as long as they get a priority check-in and baggage allowance would they really mind sitting in economy for a 1 hour trip? I wouldn't.
There is a regular domestic flight I use in Thailand which rarely has anyone in busy class at all. They still pull the curtains, mind!
Or maybe I would as well if I was cabin crew to stop both toilets being used.
Another first the other day on AMS-NCL when someone was asked to stow his small paperback book for take-off.
